we have same SD Drop problems too, it will be good to seperate them if possible but i dont know,
Maybe possible to get NUmber of Successfull Location update and then;
SDCCH Drop Due to LU will be;
LU Attempt – LU Success
And SDCCH Drop without LU could be;
Total SDCCH Drops – SDCCH Drop Due to LU
could be? or too easy :))
LU success could be get only for BSC base i think, not cell base i think, right?
